Comparative Study of the Effect of Acid Etching on Enamel Surface Roughness between Pumiced and Non-pumiced Teeth.

Background: The objective was to perform a comparative analysis of the effect of acid etching on enamel roughness between pumiced and non-pumiced teeth.

Materials And Methods: The sample was composed of 32 dental surfaces divided into two groups: Group 1-16 surfaces having received pumice prophylaxis; and Group 2-16 surfaces not having received pumice prophylaxis. The teeth were kept in saline until the first record of surface roughness prior to etching.

Orthodontic treatment of a child with Crigler-Najjar syndrome type I using tacrolimus following liver transplantation.

The present study reports the orthodontic treatment of a child with Crigler-Najjar syndrome type I following a liver transplant and administration of tacrolimus (1 mg/day). Tacrolimus (FK506) is fundamental to immunosuppression following transplantation. The child exhibited Class II division 1 malocclusion.

Avulsion of permanent lower central incisors: esthetic-functional solution.

This short communication reports a clinical case of a 11-year-old girl, who underwent an avulsion of the lower left lateral incisor and who sought delayed treatment. The treatment was a combined technique with polyethylene fibers and composite resins to create a fixed partial denture, which is a low-cost solution and presents a good esthetic-functional result. The technique is described and the success of its use in appropriately recommended cases is confirmed.

Seven-year follow-up of esthetic alternative for the restoration of peg-shaped incisors: a case study of identical twins.

Alterations in tooth shape and size are related to impaired esthetic appearance and facial harmony and can have a negative effect on a patient's self-esteem. Many alternatives for treating peg-shaped teeth are described in the literature. This article presents two clinical cases involving peg-shaped lateral incisors that were transformed with composite resins, addressing aspects related to treatment alternatives and facial esthetics.
